Problems solved by technology

[0004] After the emergence of SDN, it has been paid attention to and applied in many aspects. However, how to introduce and combine SDN technology in the traditional IPv6 transition technology to solve the complexity of the network and the sustainability of the service in the coexistence stage of IPv4 and IPv6 has not yet been too in-depth.

Abstract

The invention provides an IPv4 and IPv6 interconnection system based on an SDN. The method comprises the following steps: compiling IPv4 and IPv6 interconnected application software by using a standard control interface provided by a control plane by utilizing a SDN technical means, realizing protocol translation and address conversion of an IPv4 data packet and an IPv6 data packet, and then installing and configuring the IPv4 data packet and the IPv6 data packet into an SDN controller. The mode is simple and convenient to configure, and the original network device does not need to be functionally modified. When the requirement for interconnection of the IPv4 and the IPv6 is not needed, only the function of interconnection of the IPv4 and the IPv6 needs to be removed from the controller, and the influence on the network is very small. According to the invention, the debugging test of the network function becomes flexible and convenient, even if some network application functions are not needed in the future, only the related application modules need to be removed from the controller, and the influence on the network is very little.

Description

technical field [0001] The invention relates to an SDN-based IPv4 and IPv6 interconnection system Background technique [0002] With the expansion of network scale and the emergence of various new applications, more and more problems are exposed in IPv4 networks, such as exhaustion of IPv4 addresses, security problems, QoS (Quality of Service) problems, and inconvenient configuration. These problems have seriously hindered the development of the current Internet, so a new IPv6 protocol was designed. However, it will cost a lot to completely upgrade the current IPv4 network to an IPv6 network, so IPv4 and IPv6 will coexist in a long period of time in the future. In order to ensure the continuity of network services, IPv6 transition technology must be introduced during the coexistence stage of IPv4 and IPv6. Each of the transition technologies currently in use is specific to a specific application and is not universal. Therefore, in actual deployment, devices with correspon...
